To all whom it may concern.-

Be it known that l, BERNARD ORossLEY, a subject of the King of Great Britain,and a resident of Bnrnley, in the county of Lancaster and Kingdom of Great Britain, have invented newand useful Improvements in Shuttles for Looms, of which the following is a specification.

This invention relates to shuttles for automatic filling-replenishing looms, in which on the failure of the filling in the shed a fresh filling-case is inserted into the shuttle from one side and the spent case pushed out on the other side; and it consists in an improved construction of shuttles for such looms. One very great difficulty experienced in said looms is caused by the fact that the shuttle does not come to a stop in the shuttle-box always in the same place, the positions in thebox at which it stops diifering in ordinary calicolooms by as much as an inch and a half. In order to place the shuttle into the position required for a fresh filling-case to be inserted into it and the spent case to be ejected, special shuttle-positioning devices have hitherto been used in such looms, which complicates the mechanism and gives rise to repairs and derangements. I

The object of this invention is to obviate the necessity of any such positioning devices, which object is attained by so constructing the shuttle that it can receive a cylindrical filling case or shell, hereinafter called shell, in any position at which it comes to rest in the box and that the shell is secured in its proper position in the shuttle bythe first two picks made with it.

On the drawings annexed hereunto, Figure 1 shows a top view of the shuttle with a filling case or shell in position; Fig. 2, a longitudinal vertical section; Fig. 3, a longitudinal horizontal section, and Fig. 4 a cross-section, of the same without the shell.

In accordance with this invention the through-slot of the shuttle a is made longer than the filling-shell b by the length of the difference in the positions at which the shuttle stops in the shuttle-box and such additional clearance as may be required. For ordinary calico-looms the length of the slot from c to d would be, say, two inches longer than that of the shell I).

Along one side of the'slot there is placed a spring 6, fixed, preferably, at the end d of the slot by a screw f to the shuttle, the other end being bent to enter a notch-at the end a. At the back of the spring the shuttle is recessed for the same. This spring will yield when a cylindrical shell is pushed into the slot at any place therein and press the shell into the concave recess g, formed in the opposite side of the slot. On the spring 6 a projection is formed, which can seize behind the end of the shell 6 when its other end is close to the end 0 of the slot. The projection t' may be either directly or indirectly attached to the spring e; but I prefer to attach it to the end of a light spring-blade h, riveted to the back of the spring 6, so as to protrude through a hole in the latter, as shown. This stud is beveled on the side from which the shells are put into the shuttle.

When. the change of filling is to be made, a fresh shell can be pushed into the shuttle by the changing motion, whether the shuttle comes to rest at one point of the shuttle-box or the other, within the limits in which the position of the shuttle varies, the spring e and the stud 'i yielding and entering the recess in the side I of the shuttle. The shell I) is put in with the filling passing out of the same at the end b, which end is directed to the outer .end of the shuttle-box and by being pushed in ejects the spent shell. When the change is effected, the shuttle is first picked from the end m and passes through the shed to the opposite shuttle-box, where itis stopped by the usual means. The moment of inertia imparted to the shell by this pick then causes it to .slide between the cavity gin the side and the spring 6 to the end d of the slot. When the shuttle is next picked back and comes to rest in the shuttle-box, the shell slides to the end 0 and the spring-stud tor equivalent projection onthe spring 6 snaps behind the end b and thereby locks the shell in the shuttle in the position shown on Fig. 1..

In cases where the shell is pushed into the shuttle from below'the ends of the same are hollowed out, as shownby Figs. 2 and 4c,- for the filling to run under the shuttle. The filling passes out of a central hole in the shell and between its end I) and the end 0 of the slot, making a rectangular bend, and makes a second rectangular bend around the edge of the end 0 when the shuttle is picked in one direction and around the edge of the end I) when the shuttle is picked in the other direction, which puts sufficient tension on the filling. Any suitable shuttle self-threading device may be applied at the end 0, if preferred, in cases where the shell is put in from the top or side of the shuttle.

I claim as my invention 1. A shuttle for filling-replenishinglooms having a slot and a filling-shell adapted to be contained therein, said slot being longer than the filling-shell by more than the difference in the positions at which the shuttle comes to rest in the shuttle-box.

2. A shuttle for filling-replenishing looms having a slot, at filling-shell adapted to be contained therein, said slot being longer than the filling-shell by more than the diiference in the positions at which the shuttle comes to rest in the shuttle-box, a concave recess on one side of the slot and a square recess at the opposite side, a flat spring along the latter side adapted to enter said recess and having a projection attached to it adapted to hold said fillingshell against one end of said slot.

3. The combination with a shuttle for filling-replenishing looms having a slot, a cylindrical filling shell adapted to be contained therein, said slot being longer than a fillingshell by more than the diiference in the positions at which the shuttle comes to rest in the shuttle-box, and having a concave recess on one side of said slot, of a flat spring on the opposite side of said slot and extending along one side thereof and adapted to press said shell into said concave recess, and a projection on said spring adapted to hold said shell against one end of the slot.

4. In a shuttle for'filling-replenishin g looms having a slot therein, a cylindrical fillingshell adapted to be contained in said slot, said slot being of a length greater than a fillingshell by more than the difiierence in the positions at which the shuttle comes to rest in the shuttle-box, a concave recess on one side of said slot adapted to fit the cylindrical fillingshell, a fiat spring extending along the opposite side of the slot and fixed to the shuttlebody and having a spring-blade riveted to it, a stud on said spring-blade passing through a hole in said fiat spring and adapted to be pushed back by a filling 7 shell entering the slot, and also adapted to hold the shell against one end of the slot.

5. A shuttle for filling-replenishing looms having a slot, a filling-shell adapted to be contained therein, and means carried by said shuttle for retaining said shell in said slot, said slot being longer than the shell by more than the difference in the positions at which the shuttle comes to rest in the shuttle-box.

(3. A shuttle for filling-replenishing looms having a slot, a filling-shell adapted to be contained therein, and means for resiliently retaining said shell against transverse movement in said slot, said slot being longer than the shell by more than the diii'erence in the positions at which the shuttle comes to rest in the shuttle-box.

7. A shuttle for filling-replenishing looms having a longitudinal slot therein, a fillingshell adapted to be contained in said slot, and means at the sides of said slot for holding said shell against transverse movement therein, said slot being longer than the shell by more than the difference in the positions at which the shuttle comes to rest in the shuttle-box.

8. A shuttle for filling-replenishing looms having a longitudinal slot therein, a fillingshell adapted to be contained in said slot, and means at the sides of said slot for holding said shell against transverse movement therein, said slot being longer than the shell-by more than the difference in the positions at which the shuttle comes to rest in the shuttle-box, and means operated by the motion of the shuttle for securing the shell against longitudinal movement in its slot.

9. A shuttle for filling-replenishing looms having a slot, a filling-shell adapted to be contained therein, and means carried by said shuttle for retaining said shell in said slot, said slot being longer than the shell by more than the difference in the positions at which the shuttle comes to rest in the shuttle -box, and means operated by the motion of the shuttle for securing the shell against longitudinal movement in its slot.

10. A shuttle for filling-replenishing looms I having a slot, a filling-shell adapted to be contained therein, means for resiliently retaining said shell against transverse movement in said slot, said slot being longer than the shell by more than the diiference in the positions at which the shuttle comes to rest in the shuttle-box, and means operated by the motion of the shuttle for securing the shell against 1ongitudinal movement in its slot.

11. A shuttle for-filling-replenishing looms having a longitudinal slot therein, a fillingshell adapted to be contained in said slot, means at the sides of said slot for holding said shell against transverse movement therein, said slot being longer than the shell by more than the difference in the positions at which the shuttle comes to rest in the shuttle-box, and means operated by the motion of the shuttle for securing the shell against longitudinal movement in its slot.

In testimony whereof I have hereunto signed my name in the presence of two witnesses.
